Claude Usage Checker
v1.3.0Check Claude Code / Claude Max usage limits. Run when user asks about usage, limits, quota, or how much Claude capacity is left.
Claude Usage Checker
Launches the Claude CLI interactively (PTY) and reads the /usage output to report your Claude Code / Claude Max quota.
Prerequisites
- Claude CLI must be installed (
npm i -g @anthropic-ai/claude-code) and logged in - If running
claudeshows "Missing API key", the user must log in manually first: open a terminal, runclaude, and complete the browser login flow - Requires an interactive PTY — the agent will launch a local process and read its output (quota info only)
Steps
- Launch
claudewith PTY - Wait for the welcome screen (poll until it appears)
- Send
/usage+ Enter - Read the output (poll until usage data appears)
- Close with Escape then
/exit - Report the results
Commands
# Launch claude with PTY
exec pty=true command="claude"
# Wait and check log
process action=poll sessionId=XXX timeout=5000
# Send /usage
process action=send-keys sessionId=XXX literal="/usage"
process action=send-keys sessionId=XXX keys=["Enter"]
# Read output
process action=poll sessionId=XXX timeout=5000
# Exit
process action=send-keys sessionId=XXX keys=["Escape"]
process action=send-keys sessionId=XXX literal="/exit"
process action=send-keys sessionId=XXX keys=["Enter"]
Notes
- If you see "Missing API key" → tell the user to log in; browser-based login won't work headlessly
- Allow a few seconds between polls — Claude CLI starts slowly
- "Current week" = weekly reset, not daily
Output Format
Report in a table:
| Usage | Resets | |
|---|---|---|
| Current session | X% used | today at HH:MM (timezone) |
| Weekly (all models) | X% used | HH:MM (timezone) |
| Weekly (Sonnet only) | X% used | HH:MM (timezone) |
| Extra usage | X% used / $X of $Y spent | date (timezone) |
Always show reset times. The CLI displays them as "Resets Xpm" — convert to HH:MM format.
